Hello, Thank you for your replies. I was familiar with the "Survex Aven" method, but it was "Distance along the survey legs between these points" that I was looking for. The method proposed by Benedikt Hallinger (shortestPath.py) works very well. I'm currently unable to compile "survex-dist" (I get an error), the method proposed by Alastair Gott.

Hi, I once found a GPL2 library called "survex.py" from Thomas Holder. Using that it is possible to find the shortest path (as you walk) between two points. Survex itself just shows the shortest path as the crow flies.
I made a convinience wrapper "shortestPath.py" for the task, call example (linux): $ ./shortestPath.py Hirlatzhoehle.Zubringer.1.1.0 Hirlatzhoehle.Alter_Teil.2.1.55 ('Shortest route length:', 2214.546790435116, 'm') ('Cumulated height going upwards:', 354, 'm') ('Cumulated depth going downwards:', -196, 'm')
I hope its useful, greetings, Beni

Hello,
I'd like to know if there's a method for calculating the distance between two survey station, and also for identifying the shortest path, or even for determining all possible paths. I think this should be possible using the .slq file.
thanks
